Word has preformatted combinations of fonts, colors, and paragraph
formatting. Apply a Quick Style from the gallery, customize the existing styles,
or create your own.

Apply a Quick Style after the document is written.

If you are using a file that was created in Office 2003, you MUST save it as
a Word 2007 or 2010 format.
As you create new files add 07 at the beginning or end of your files.
As you will have 2003 and 2007 files in your folder, I suggest that you tag the
07 or 10 files.
Example: jfkinaugural07
